Believe it or not I have this game running, somewhat, on a Steam Deck. Didn't need to do much tinkering, but do use Proton Experimental. One thing I've never figured out is how to load into other zones. I get the same Lowlevelfatalerror every time I try to leave the first forest area. What adjustments did you make in the ini file?
From the crack guide:
4. * Edit
UE4SS-Settings.ini file that came with mod. You need to find setting called
HookCallFunctionByNameWithArguments and disable it by changing its value from
1 to
0.
* I am not sure if that is mandatory but without modifying this setting game hangs on launch on my Linux machine under WINE. Possibly that's a Linux specific quirk and may not be required on Windows
I've been able to play it and transition zones but it is very fragile. General stability improved once I changed to lower end anti-aliasing and I turn off bloom, motion blur, and depth of field in any game that has them.
When it starts it's full screen windowed and then adjusts to 1920x1080. If I try to resize again it will usually crash. Sometimes I have to start it several times before it makes it past that first resolution change. Once it's there I'm in pretty good shape so long as the window does not ever lose focus.
I'm using lutris with a ge-proton prefix, msvc++, and corefonts installed.
